Which condition is known for having a central solid mass?

The condition characterized by a central solid mass is the malignant stellate tumor. This type of tumor typically presents with irregular margins and a central solid component, which is commonly noted in imaging studies. The stellate appearance arises from the tumor's infiltrative growth pattern, with extensions radiating from the central mass, resembling a star.

In the context of breast imaging and pathology, recognizing the specific characteristics of malignant masses is crucial for accurate diagnosis and treatment planning. The presence of a central solid mass in a malignant stellate tumor often indicates advanced disease and the potential for metastasis.

In contrast, conditions such as fat necrosis or hamartoma may exhibit different imaging features. Fat necrosis often appears as a lumpy or irregular mass but is not characterized solely by a central solid structure, as fat necrosis may contain varying types of tissue densities that can complicate its imaging appearance. A hamartoma, on the other hand, typically demonstrates a combination of fat and glandular tissue, presenting as a well-circumscribed mass rather than a central solid form. Lastly, a star-shaped cyst would not be recognized for having a solid central mass but rather would be characterized by fluid content, which differentiates it from the malignant stellate tumor.
